Pre-COVID life expectancy, mortality, and burden of diseases for adults 70 years and older in Australia: a systematic analysis for the Global Burden of Disease 2019 Study

Summary Background The Australian population aged 70 and above is increasing and imposing new challenges for policy makers and providers to deliver accessible, appropriate and affordable health care. We examine pre-COVID patterns of health loss between 1990 and 2019 to inform policies and practices. Methods Using the standardised methodology framework and analytical strategies from GBD 2019 methodologies, we estimated mortality, causes of death, years of life lost (YLLs), years lived with disability (YLDs), disability-adjusted life years (DALYs), life expectancy at age 70 and above (LE-70), and healthy life expectancy (HALE-70) in Australia comparing them globally and with high socio-demographic index (SDI) groups. Findings DALY rates have been improving steadily over the past 30 years among Australians aged 70 and above. Decreases in DALY rates were primarily attributed to a fall in YLLs attributable to cardiovascular diseases (60%) and chronic respiratory disorders (30.2%) and transport injuries (56.9%), while the non-fatal burden remained stable from 1990 to 2019. According to the DALY rates, the top five leading causes are ischemic heart disease, Alzheimer's disease, COPD, stroke, and falls, where falls exhibited the largest increase since 1990. Interpretation This study provides an in-depth report on the main causes of mortality and disability in Australia's population aged 70 and above. It sheds light on the shifts in burden over three decades, emphasising the need for the Australian health system to enhance its readiness in addressing the escalating demands of an ageing population. These findings establish pre-COVID baseline estimates for Australia's population aged 70 and above, informing healthcare preparedness. Funding Bill & Melinda Gates Foundation.


Introduction
Older people account for an increasing share of the total Australian population. 1 Over the 20 years between 1999 and 2019, the proportion of the Australian population 65 years and over increased from 12.3% to 15.9%, which is higher than the global estimate of 9%. 2 Ageing of the population puts unsustainable pressure on public spending and subsidised health care, [3][4][5] which was exacerbated significantly by the COVID-19 pandemic. 6everal studies reporting that Australian health systems falls short when it comes to providing adequate care for older Australians 7 especially for culturally and linguistically diverse populations 8 as well as in rural areas, where waiting times for medical care are long. 9he common occurrence of multimorbidity in older individuals 8,[10][11][12] and the challenge of aligning financial incentives in a mixed public-private health care and financing system, 9 further amplifies the difficulty in accessing treatment.In acknowledgement of this need the Australian government has recently announced new policy commitments to strengthen primary health care for the elderly.This includes significant local investment in a new chronic disease care funding model for those aged 70 years and above ($448.5 million over two years from 2020 to 21) and the Practice Incentives Program Quality Improvement Initiative, including retention of the Aged Care Access Incentive ($201.5 million over five years) and the Dementia, Aging and Aged Care Mission ($167.5 million over 10 years starting in 2019-2021).The research spending on aged health has been allocated $45.9 million dollars in 2019 up from $32.1 million in 2013 (NHMRC).
For appropriate policy planning and targets for research, detailed timely updates on disease burden and expenditure by age and by disease, are critical.Such data is particularly important as a baseline pre the impact of the coronavirus 2019 (COVID-19) pandemic, where older adults had the highest risk of severe disease, hospitalisation, and death.
Currently, the main source for Australian Government health-related budget allocations and decision making are the estimates produced by The Australian Institute of Health and Welfare (AIHW), which introduced the Australian Burden of Disease Study (ABDS) through a series of reports in 1996, 2003,  2011, 2015, and 2018.While the ABDS provides a coverage of burden estimates at sub-national level, the most recent 2022 estimates for 220 conditions 13 providing incomplete information about trends over time, which are also not directly comparable with those produced earlier or by other institutions (mainly, due to differences in methodology and applied data resources).These limitations affect timely decision making.
The Global Burden of Disease Study 2019 offers consistent country-specific disease burden data, enabling cross-location and time point comparisons. 14With yearly data since 1990 and international collaboration, it aids between-country assessments and modelling for local insights.In this study, our primary objectives are to analyse Australia's GBD 2019 estimates, focusing on the 70 years and above population.We aim to track trends and make comparisons with the estimates for high Socio-Demographic Index (SDI) countries group, across key GBD metrics. 14These findings are crucial for timely, evidence-based insights into health loss among the 70 and above population, facilitating policy impact assessment, effective prevention and treatment strategies, and healthcare resource planning.

Research in context
Evidence before this study Australia's healthcare system is globally renowned for providing high-quality care to individuals aged 70 and over.With some of the highest life expectancies and a high quality of life on a global scale, Australia's commitment to the wellbeing of its senior citizens is evident.However, it is essential to acknowledge the substantial increase in per capita health expenditure over recent decades, which currently ranks among the highest worldwide.The advent of COVID-19 has added new challenges to the Australian healthcare system, particularly affecting one of the most vulnerable populations: those aged 70 and over.To maintain the delivery of effective and high-quality care and to guide preventative measures for the well-being of the 70 and above population, it is crucial to understand the burden of disease for this demographic and how these trends have evolved over time.The Australian Institute of Health and Welfare introduced the Australian Burden of Disease Study (ABDS) through a series of reports (1996, 2003, 2011, 2015,  2018), with the most recent one published in 2022.These reports aimed to assess the burden of disease in Australia and compare it with previous findings.However, it is important to note that the ABDS 2022 study solely provided point-in-time estimates for 220 conditions, offering an incomplete perspective on temporal trends.Furthermore, this study did not specifically analyse the population aged 70 and over, overlooking a critical demographic.Additionally, these individual studies did not account for potential confounding factors or differences across different study periods.Lastly, these estimates are not directly comparable with international studies due to variations in methodology.To address these limitations and enhance the depth of our understanding, our study relies on standardised, globally recognised estimates sourced from the Global Burden of Disease 2019 Study.

Added value of this study
Our study represents a comprehensive analysis of the disease burden in the Australian population aged 70 and over, employing standardised and globally comparable metrics.We provide a thorough assessment of life expectancy, mortality, and the burden of diseases for adults aged 70 and older in Australia from 1990 to 2019, offering a nuanced and internationally comparable perspective on the health of Australians aged 70 and over.This study establishes crucial pre-COVID baseline estimates for Australia's population aged 70 and over, thereby informing healthcare preparedness.

Implications of all the available evidence
Estimates of disease burden in Australia serve as invaluable evidence to guide population health policies and prioritise healthcare initiatives.As life expectancy at birth steadily rises and mortality rates decline, the burden of disease in Australia increasingly encompasses functional health challenges associated with aging.This includes the top five leading causes of DALYs: ischemic heart disease, Alzheimer's disease, COPD, stroke, and falls, with falls exhibiting the most significant increase since 1990.To ensure the long-term sustainability of the Australian healthcare system, it is imperative to implement preventive and remedial healthcare policies and practices that specifically target these pressing issues.

Overview
We analysed data of the GBD 2019 study to evaluate Australian trends in epidemiological patterns and disease burden for people aged 70 years and older for 1990-2019.The analyses employed established GBD 2019 summary measures of morbidity and mortality, including death rates, years of life lost (YLLs), years lived with disability (YLDs), disability-adjusted life years (DALYs), life expectancy at 70 (LE-70), and health adjusted life-expectancy aged 70 (HALE-70).Seventy years and older is the GBD cut-off used to define old age.This threshold was selected based on literature (a historical threshold reflecting the Social Security Act, 1991), 15 the availability of pre-determined age groups in the GBD study, and to provide comparable findings to the majority of studies on older people.Current GBD estimates are available in public domain and can be accessed: https://vizhub.healthdata.org/gbd-compare/.This manuscript adheres to the Guidelines on Accurate and Transparent Health Estimate Reporting. 16

Input data sources
Input data were extracted from censuses, household surveys, civil registration and vital statistics, disease registries, health service use, disease notifications, health surveys, administrative databases, and other sources.The Global Health Data Exchange, GHDx, source tool is publicly available to identify a complete list of 1020 data sources used for estimating any disease or injury outcome in Australia (https://ghdx.healthdata.org/gbd-2019/data-input-sources).(Full list in Supplementary Table S1).

GBD measures
Below, we provide a concise overview of each measure of the GBD 2019.For a comprehensive understanding of the methods employed in the GBD demographic estimation process, detailed descriptions can be found in previous publications. 14,17,18In the GBD 2019 study, causes of mortality and morbidity were organised into a levelled cause hierarchy from the broadest causes of death and disability at Level 1 to the most specific causes at Level 4 defining 369 diseases and injuries, which were aggregated in three Level 1 causes, 22 Level 2 causes, 174 Level 3 causes, and 301 Level 4 causes.In total, 364 total causes are non-fatal and 286 are fatal.The full GBD cause hierarchy, including corresponding International Classification of Diseases (ICD)-9 and ICD-10 codes, is published in detail previously. 14nly the top 20 causes of deaths, YLLs, YLDs, and DALYs, selected based on the GBD ranking estimates, are presented in our analysis.In the Results section, we used the Level 3 cause categorisation, providing a balance between specificity and comprehensiveness, unless otherwise specified.
Cause-specific death rates and cause fractions were derived using advanced statistical techniques, namely the Cause of Death Ensemble model and spatiotemporal Gaussian process regression.To ensure accuracy, causespecific deaths were adjusted to align with the total all-cause deaths calculated in the broader GBD framework, which includes population, fertility, and mortality estimates.Years of life lost (YLLs), defined as the number of years of life lost due to premature death, defined as dying before reaching the estimated life expectancy for a specific population, were computed by multiplying the adjusted cause-specific deaths by the standard life expectancy at each age.
To maintain consistency across various measures, a Bayesian meta-regression modelling tool DisMod-MR 2.1 was employed.This tool facilitated the harmonisation of incidence, prevalence, remission, excess mortality, and cause-specific mortality for most causes.By multiplying prevalence estimates with disability weights 19 assigned to distinct disease sequelae and injuries, years lived with disability (YLDs), defined as one YLD is one year of health life lost, were estimated.This approach ensured the inclusion of the impact of different health conditions on overall disability burden.
Disability-adjusted life years (DALYs), a measure of healthy life lost due to premature death or living with disability, were calculated by summing YLDs and YLLs for each disorder.One DALY equates to one lost year of healthy life.
Life expectancy at age 70 (LE-70), is defined as the number of years a person can expect to live once he/she reaches a 70-year-old mark, and was estimated based on expected mortality rates using the meta-97 regression tool MR-BRT (meta-regression-Bayesian regularised trimmed) to analyse the relationship between log mortality rates and SDI. 14,20Healthy adjusted life expectancy (HALE-70) is an estimation of the number of remaining healthy years a 70-year-old can expect to live.It serves as a summary metric for both the age-specific mortality and morbidity for a given population in a calendar year.We followed the analytical methods used to generate HALE in the GBD 2017 cycle. 21

Uncertainty intervals (UI)
For all results, we report 95% uncertainty intervals (UIs) derived from 1000 draws from the posterior distribution of each step in the estimation process according to the established GBD methodology.We present sex-specific rates per 100,000 population aged 70 and above, and percentage changes from 1990 to 2019 for deaths, YLLs, YLDs, DALYs, and deaths for 20 top causes.

Comparison with high socio-demographic index GBD group
Socio-demographic Index (SDI) is a composite indicator of development status strongly correlated with health outcomes.It is the geometric mean of 0-1 indices of total fertility rate under the age of 25 (TFU25), mean education for those ages 15 and older (EDU15+) and lag distributed income (LDI) per capita.It is expressed on a scale of 0-1, with 0 being the lowest SDI value and 1 being the highest.The high SDI group in 2019 consists of 38 countries (including Australia) with the SDI index values above 0.805.The list of high SDI countries and their yearly SDI values is provided in the Supplementary Table S2.We compared the burden of disease in Australia with the average of high SDI group and global estimates. 22

Results
Life expectancy (LE-70) and healthy adjusted life expectancy at age 70 and above (HALE-70), mortality at ages 70 and above, and decomposition of causes of death Over the past thirty years, life expectancy at age 70 (LE-70) in Australia has risen for both males and females.In 1990, males had a LE-70 of 12.1 years (95% UI: 12.0-12.1),which increased to 16 years (95% UI: 15.8-16.1) in 2019.For females, LE-70 went from 15.3 years (95% UI: 15.3-15.4) in 1990 to 18.3 years (95% UI: 18.2-18.4) in 2019.This narrowing gap between males and females decreased from 3.2 years in 1990 to 2.3 years in 2019.When considering years lived in poor health, HALE-70 in 2019 showed little difference between males (11.1 years (95% UI: 9.9-12.1))and females (12.4 years (95% UI: 11-13.6)).However, the annual percent change from 1990 to 2019 was higher for males (0.88%) than females (0.51%), suggesting a narrowing gender gap in LE-70 and HALE-70 in Australia, consistent with global patterns.Decomposition analysis of the increase in Life Expectancy (LE) from 1990 to 2019 indicates that the top three causes contributing to the LE increase are cardiovascular diseases (+3.5 years), neoplasms (+0.9 years), and transport injuries (+0.4 years).Substance use, on the other hand, contributes to a decrease in LE (−0.1 years).For more detailed information, refer to Supplementary Table S3.
Despite a 75.9% increase in the absolute number of deaths among those aged 70 and above in Australia from 1990 to 2019, reflecting population growth and aging, the all-cause mortality rate decreased by 24% from 6097 deaths per 100,000 (95% UI: 6065-6129) in 1990 to 4636 deaths per 100,000 (95% UI: 4563-4713) in 2019.This reduction was more pronounced in males (30.9%) compared to females (18.8%), consistent with a global decrease of 20.5% (22.5% in males and 19.7% in females) for the same period.Simultaneously, there is an overall LE-70 increase of 0.74% in this pattern from 1990 to 2019.However, it's noteworthy that the percentage change has decreased over the past decade, with a 0.97% increase in 1990-2000, a 0.92% increase in 2000-2010, and only a 0.29% increase in 2010-2019.

Leading causes of YLLs among those aged 70 and older
In the last three decades, Australia witnessed a substantial 35.6% decrease in total fatal burden among adults aged 70 and above, declining from 78,550 (95% UI: 78,131-78,984) YLLs per 100,000 in 1990 to 50,585 (95% UI: 49,729-51,502) YLLs per 100,000 in 2019.This remarkable decline was primarily driven by reductions in YLLs attributed to cardiovascular diseases (−60%), chronic respiratory diseases (−30.2%), and transport injuries (−56.9%)(Level 2), collectively accounting for 39.5% of the total fatal burden in 2019.The leading cause of Level 2 fatal burden in Australia in 2019 was neoplasms, followed by cardiovascular and neurological diseases (particularly Alzheimer's, a Level 3 cause), constituting 73.3% of the total fatal burden.
Ischemic heart disease remained the primary cause of Level 3 fatal burden among older adults in Australia Consistent with trends for ischemic heart disease, the YLLs rate significantly decreased for stroke, COPD, colorectal cancer, diabetes, breast cancer, lymphoma, stomach cancer, aortic aneurysm, cardiomyopathy, and upper digestive diseases from 1990 to 2019.In 2019, several sex-specific differences emerged: fatal burden attributable to COPD, lung cancer, colorectal cancer, diabetes, lymphoma, and stomach cancer was notably higher in males than females.However, no sex-based difference was observed in YLLs attributable to stroke.The decline in YLLs rate for stroke, COPD, breast cancer, and stomach cancer in Australia from 1990 to 2019 mirrored global estimates (Fig. 1).

Leading causes of YDLs among those aged 70 and older
The total non-fatal burden among older adults aged 70 and above in Australia remained stable over three decades, standing at 27,913 (95% UI: 21,067-35,438) YLDs per 100,000 in 1990 and 28,596 (95% UI: 21,754-36,033) YLDs per 100,000 in 2019.Musculoskeletal disorders maintained their status as the leading group of causes for disability burden in 2019 (19% of total YLDs), followed by unintentional injuries (13.6% of total YLDs), sense organ diseases (11.7% of total YLDs), cardiovascular diseases (8.9% of total YLDs), and diabetes and kidney disease (8.8% of total YLDs), collectively contributing to 62% of total non-fatal burden (Level 2).The top 20 causes of YLDs at Level 3 for 1990 and 2019 are detailed in Fig. 2.
However, there was no significant increase in the rate of YLDs attributed to falls for both males and females over the past 30 years.Age-related hearing loss, the leading cause of YLDs in males in 2019, accounted for 10.5% of total male YLDs and exhibited no significant difference from 1990 (1990: 3207 YLDs per 100,000, 95% UI: 2264-4413; 2019: 2931 YLDs per 100,000, 95% UI: 2018-4055) (Fig. 2).

Total health loss burden for those 70 and older in Australia
In line with global trends, Australia witnessed a 25.6% reduction in the overall health burden among individuals aged 70 and older, measured in DALYs.This decline occurred over the past three decades, with figures dropping from 106,463 DALYs per 100,000 (95% UI: 99,705-11,388) in 1990 to 79,181 DALYs per 100,000 (95% UI: 72,239-86,535) in 2019.This trend was consistent for both sexes (Table 2).Notably, while there was a decrease in the health burden attributed to cardiovascular diseases (56.1%), neoplasms (13.6%), and chronic respiratory diseases (21.5%) between 1990 and 2019, these conditions remained the primary causes of disease burden for Australians aged 70 and above in 2019, collectively representing 53% of total DALYs.
Over the past three decades, while certain causes decreased their contribution to DALYs, there was a 19.7% increase in DALYs attributed to Alzheimer's disease (AD).Figures rose from 4206 DALYs per 100,000 (95% UI: 1913-9449) in 1990 to 5033 DALYs per 100,000 (95% UI: 2290-10,655) in 2019, although with wide overlapping uncertainty intervals, warranting cautious interpretation.A similar trend was observed in global and high SDI country estimates.
The most substantial increase (67.4%) in total burden over the last three decades was associated with falls, surging from 2117 DALYs per 100,000 in 1990 (95% UI: 1690-2682) to 3542.DALYs per 100,000 in 2019 (95% UI: 2838-4419), consistent for both males and females.This rise primarily stemmed from increased YLLs due to falls.
For a comparison of the top 20 sex specific DALYs between global estimates, Australia, composite scores of the 'High SDI' group of 38 countries, and selected 14 individual countries, please refer to Supplementary Figures S3 and S4.

Discussion
The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) is the most comprehensive scientific effort to quantify fatal and non-fatal disease burden worldwide.Our analysis of Australian data shows that the health of the 70 and older age group has steadily improved over the past 30 years, as indicated by decrease in both YLL and DALY rates.Overall life expectancy is increasing, largely due to improved longevity in males and specifically driven by a reduction of YLLs attributable to cardiovascular (60%) and chronic respiratory (30.2%) diseases, and a substantial reduction in transport injuries (56.9%).
Despite an overall reduction in DALY rates, the absolute number of DALYs for this group is rapidly growing (72.4% increase from 1990 to 2019) with the   increasing older population.As a word of caution for policy makers we urge to remain aware that the absolute number of DALYs, and not the DALY rates, represents the total burden of disease that the Australia's health system must manage and prepare for it to continue to increase.While there have been substantial improvements in DALYs for cardiovascular diseases, neoplasms, and chronic respiratory diseases, the burden of illness remains high.Policy targeting risk reduction, screening and evidence-based intervention is needed to optimise healthy aging and minimise personal, social and economic burden. 23While some environmental and lifestyle risks are on the whole decreasing, for instance smoking, others like poor air quality are worsening 24 and require urgent coordinated intervention.Particularly, addressing inequity in access to health care and healthy lifestyles for minority groups and rural populations is critical 25,26 to target excess modifiable burden.Taking a life course approach and designing interventions to modify risk from middle age may provide the best outcomes beyond 70 years of age. 27Innovation in digital monitoring, telemedicine and in home support services may contribute to future gains by enabling healthy independent living. 28alls in older people are one of a major public concern due to the associated morbidity and the cost to health services.We found a large increase in DALY rates attributed to falls across 1990 to 2019 in Australia, now caught up with many other high SDI countries (see Supplementary Figures S3 and S4 for details) to match the global average.These high GBD estimates of 2% in males and 1.7% in females annual increase of DALY rates attributed to falls over the last thirty years corresponds with a report by the Australian Institute of Health and Welfare on the trends of hospitalised fall-related injuries in older people (above 65 years) from 2006 to 2007 to 2016-2017, which showed across that 10-year period, yearly fall-rates increased by 3% for males and by 2% for females.The causes of falls are multifactorial, involving both intrinsic and extrinsic factors.In particular, fall injury risk has been associated with female gender and number of physical and lifestyle-related factors, such as the presence of chronic health conditions, like stroke, having mobility problems, polypharmacy, alcohol consumption, vision loss 29 and a low body mass index. 30urthermore, it's worth noting that Musculoskeletal Disorders (MSD), which continue to be the primary cause of disability burden (accounting for 19% of total YLDs), are well-known contributors to falls. 31There is also a potential link between falls and use of specific drugs that impair mobility, including antipsychotics. 32otential overuse and misuse of antipsychotics in older persons including those with dementia has been a longstanding concern in Australia.Starting with the 2005 'Dementia Initiative', also known as the 'Dementia -A National Health Priority Initiative' (Department of Health, 2005), the Australian government has implemented a number of strategies and policies to address this issue. 33These interventions have produced only modest results, and a recent audit suggests that compliance with the Australian Government subsidised Pharmaceutical Benefits Scheme (PBS) guidelines, limiting antipsychotic use to last resort and for 12 weeks only, is limited. 34Although there was an overall increase in falls between 1990 and 2019, we do observe the YLLs and YLDs rates for falls beginning to slowly decrease around 2015, suggesting either that the impact of falls and management of complications is improving.
In examining the trends of chronic kidney disease (CKD) from 1990 to 2019 among individuals aged 70 and over, our data reveals a 44.9% increase in deaths attributed to CKD, with notable gender-specific variations.Despite this significant mortality surge, the measured burden using metrics such as DALYs, YLDs, and YYLs did not exhibit a statistically significant increase during the same period.This observation prompts a deeper exploration into potential contributing factors.Plausible explanations may encompass advancements in medical management, fostering improved access to healthcare services, or alterations in CKD diagnostic criteria. 35The absence of a proportional increase in burden metrics challenges our understanding of the overall impact of CKD on this demographic.In the pursuit of a comprehensive interpretation, further investigation into the complex interplay of these factors is warranted to refine our understanding and inform targeted interventions for this vulnerable population.

Limitations
First, this study is based on GBD 2019 data and methodology, and therefore shares the limitations of the overall study, such as the major limitation of the GBD analysis of the burden of diseases and injuries being the availability of primary data.Despite having comprehensive vital registration data, Australia faces limitations in obtaining information on morbidity and health outcomes related to behavioural and metabolic risk factors.Additionally, data pertaining to inpatient and outpatient hospital admissions, health system access, and health financing were not accessible for the GBD 2019 study.Although the list of 364 causes of burden in GBD 2019 is comprehensive, some specific age-related conditions might be missing and, multimorbidity is not taken into account.While GBD provides national level estimates that are comparable with worldwide estimates, it would be highly beneficial to consider including the subnational estimates, as well as the estimates by the socioeconomic and demographic groups, such as excess mortality and decreased life expectancy of Indigenous Australians. 36

Conclusions
Despite population aging, the health of Australians aged 70 and above has improved over 30 years.However, their impact on healthcare, though, is growing.In 2019, the leading causes of DALYs were ischemic heart disease, Alzheimer's, COPD, stroke, and falls, with the latter experiencing the most significant increase since 1990, emphasising the escalating burden on Australia's healthcare infrastructure.Policymakers are urged to recognise the tangible burden conveyed by the total number of DALYs.
A life course approach, promoting middle-age health and addressing social and healthcare disparities, can enhance outcomes past 70, facilitated by digital healthcare.Falls policies for this group needs multifaceted strategies considering, comorbidity and medication misuse, especially antipsychotics.The non-fatal disease burden, including mental disorders, remained static from 1990 to 2019 in Australians over 70, underscoring the need for further promotion of healthy aging and reducing personal, societal, and economic impacts.Despite limitations, this study provides a pre-COVID baseline for understanding mortality and disease burden among Australians aged 70 and above, emphasising the ongoing need to promote healthy aging and address emerging healthcare challenges.
